Korea Zinc Signs KRW185 Billion (USD140 Million) Investment Agreement With Trafigura To Build An All-In-One Nickel Refinery

• Also enters a long-term contract to procure nickel from Trafigura, with the supply volume ranging from 20,000 to 40,000 tonnes per annum
• Investment by Trafigura, a market leader in the global commodities industry, provides a reliable source of nickel, a key material for secondary batteries^*
• Yun B. Choi, Chairman of Korea Zinc, stated “Through the new all-in-one nickel refinery, driven by the world’s leading refining technologies, Korea Zinc will further strengthen its position in the global nickel market”

Highlights of the investment/supply agreements
Trafigura, a market leader in the global commodities industry, has agreed to invest in an all-in-one nickel refinery that Korea Zinc is set to establish through its nickel sulfate subsidiary, Korea Energy Materials (KEMCO). In a ceremony held on 16 November at the head office of Korea Zinc, the two companies signed an agreement to jointly invest KRW 184.9 billion (USD140 m) to establish an all-in-one nickel refinery, capable of processing a range of feedstocks including nickel matte and mixed hydroxide precipitate (MHP) with its integrated pyro-hydro process.

The investment will be used to build the nickel refinery located in Ulsan, South Korea and finance its initial working capital. Alongside the investment agreement, the two parties also entered a long-term agreement to secure a reliable supply of feedstock to the all-in-one nickel refinery. Under the contract, the amount of nickel to be supplied by Trafigura will range from 20,000 to about 40,000 tonnes per annum and Trafigura will also have the off-take right in relation to the feedstock contract.

Significance of Trafigura’s investment
Trafigura is one of the world’s largest suppliers of commodities, active in metals and minerals, oil and gas and power with revenue of KRW 400 trillion in 2022. Through its subsidiary KEMCO, Korea Zinc, known for its world-class non-ferrous metal refining technology, is teaming up with Trafigura, which is well-positioned to provide a reliable and diversified supply of nickel, a key mineral for secondary batteries. The agreement is designed to build an all-in-one nickel refinery to address global regulations such as the US Inflation Reduction Act (IRA) and fulfill customer needs by producing a wide range of products in one location.

KEMCO overview
KEMCO produces and sells nickel sulfate, one of the key raw materials used for the production of precursor. Currently, KEMCO produces up to 100,000 tonnes of nickel sulfate annually at its production facility near Korea Zinc's Onsan Smelter. Following the establishment of ‘Korea Precursor Company’, a joint venture with LG Chemical in June 2022, KEMCO plans to complete the construction of a precursor plant with an annual production capacity of 20,000 tonnes within the year and begin a test-run in 2024.

Changes in Korea Zinc’s stakes in KEMCO
Through this agreement, Korea Zinc’s stake in KEMCO increases, consolidating KEMCO’s earnings into Korea Zinc’s financial statements, and Trafigura will secure a 12.9 percent stake in KEMCO. The investment is a follow-up to the business partnership announced in November. Korea Zinc has seen an increasing number of global companies such as Hanwha, LG Chem, Hyundai Motor Group, and Trafigura joining its future growth strategy, Troika Drive.

Strengths as a nickel refiner
Korea Zinc, a global leader in non-ferrous metal production, produces 21 kinds of valuable metals and chemical products by processing various feedstock such as zinc and lead concentrates, low-grade ore and scrap metals. Korea Zinc plans to apply its technologies to the new facility to treat and process an entire range of nickel-containing materials from nickel matte to mixed hydroxide precipitation (MHP) derived from nickel laterite ore, using an integrated pyro-hydro process. Through the all-in-one nickel smelting facility equipped with cutting-edge technologies, Korea Zinc plans to treat EOL nickel-containing batteries and produce a variety of customized products, such as liquid and crystallized nickel sulfate, cobalt sulfate and precursors.
